Overview

HCPL-4200 Optically Coupled 20 mA Current Loop Receiver Data Sheet Lead (Pb) Free RoHS 6 fully compliant RoHS 6 fully compliant options available; -xxxE denotes a lead-free product Description The HCPL-4200 optocoupler is designed to operate as a receiver in equipment using the 20 mA Current Loop.
20 mA current loop systems conventionally signal a logic high state by transmitting 20 mA of loop current (MARK), and signal a logic low state by allowing no more than a few milliamperes of loop current (SPACE).
Optical coupling of the signal from the 20 mA current loop to the logic output breaks ground loops and provides for a very high common mode rejection.
The HCPL-4200 aids in the design process by providing guaranteed thresholds for logic high state and logic low state for the current loop, providing an LSTTL, TTL, or CMOS compatible logic interface, and providing guaranteed common mode rejection.
The buﬀer circuit on the current loop side of the HCPL-4200 provides typically 0.
